GRAlN-HARVESTER FRAME.

SPECIFICATION forming part of Letters Patent No. 291,449, dated January 1, 1884.

Application filed May 1, 1883. (No model.)

To all whom it may concern:

Be it known that I, CHARLES WHITNEY, residing at Sycamorain the county of De Kalb and State of Illinois, and a citizen of the p United States, haveinvented new and useful Improvements in Grain-Harvester Frames, of which the following is a full description, reference being had to the accompanying drawings, in which Figure 1 is a top or plan view; Fig. 2, a front elevation with the grain end of the platform broken off, Fig. 3, a cross-section of the brace.

This invention relates'more particularly to I 5 that class of harvesters in which the grain falls from the sickle upon a carrying-platform and is delivered therefrom to a self-binder; but it is also applicable to other forms of harvesters, and has for its object to improve the con- 2o struction of the frame, as hereinafter more specifically described, and pointed out in the claims.

In the drawings similar letters of reference indicate corresponding parts.

The front sill or finger-bar, A, may be of any of the ordinary forms of construction, provided with guards a, for the sickle, as usual,

and the carrier-platform is located between the front sill and a rear sill, A, an outer end l 3o girt or cross-sill, A, and an inner end girt or cross-sill, A and may be of the form of construction and arrangement shown, or of any other well-known form of construction and arrangement. The front sill or finger-beam, A,

in use is subjectto considerable strain, andfor this reason should be braced and supported at its inner end, and the objects of this invention are tobrace and support the inner end of the finger-beam, to furnish a bracing between the platform-frame and the drive-wheel frame,

and to support a frame for a self-binder, and these objects are accomplished by means of a single piece of iron or other material having an inclined diagonal portion and a straight horizontal portion, forming a combined front sill, bracing, and support, for the purposes named. This combined front sill, bracing, and support may be made of a piece of angle-iron or any other suitable material that can be bent or formed to have an inclined diagonal por: tion, B, and straight horizontal portion 13, the inclined diagonal portion having both a downward and a rearward bend or incline from the horizontal portion B, a downward and rearward bend at b being made for this purpose at the point where the diagonal and straight portions meet or j oin, as shown in Figs. -1 and 2. The outer end of the diagonal portion B is connected with the inner cross-girt of the carrierplatform by a suitable bracket or angle-iron, b, bolted to the end of the diagonal portion B and to the cross-sill A or the inner end can be secured to the cross-sill in some other suitable manner and by some other means than the bracket or angle-iron b, to make an attachment that is firm and secure. The diagonal portion B forms the support and brace for the inner end of the front sill or finger-beam, A, which is secured directly thereto by bolts, or which may be attached by a bracket or angle-iron, or in any other suitable firm manner. The rear sill, O, of the drive-wheel frame, as shown, supports at one end the rear sill of the platformcarrier frame by means of a standard, G and the main or drive wheel D is mounted on an axle, D, supporting by suitable bearings the cross-sills G O, to the front ends of which are secured the horizontal straight portion of the combined brace and front sill, B B, as shown in Figs. 1 and 2. It will thus be seen that with a single piece of material, B B, a front sill for the main frame, a brace and support for the inner end of the finger-beam, and

a brace for the carrier-frame are provided, the single piece forming, in fact, the front sill for the drive-wheel frame, the brace for the entire frame of the machine, and for the inner end of the finger-beam, thereby greatly simplifying the construction of the frame-work, and at the same time giving greater security against 0 strain in use. This construction and arrangement of a combined front sill and brace, in connection with the inner end of the fingerbar, furnishes a support for a binder-frame carrying a self-binder. The self-bind er is not 5 shown, as the devices composing it may be of any of the usual and well-known forms of construction and arrangement.

A form of binder-frame is shown consisting of an upper cross bar or piece, E, having at each end an arm or extension, E, and having on its front end a standard, E, the same furnishing the necessary support for the driving-shaft, binder-arm shaft, and other devices. This frame is secured at its lower end to the diagonal portion of the brace by a foot orrest, E, which is bolted or otherwise secured to a rail-brace, and it is attached to the fingerbeainby a foot or rest, E, which may be bolted or otherwise secured to such beam.

With other forms of binder-frame, the attachment to the diagonal portion of the brace B and to the finger-beam may be made in some other manner than by feet or rests; but it will be seen that the bracing and finger-beam are located in relation to each other and to the frame-work of the machine to furnish a support for the binder-frame which will be solid and firm without the addition of extra pieces or bracing, as heretofore has been required.

WhatI claim as new, and desire to secure by Letters Patent, is-

1. The combination of the main drive-wheel frame, the platform-frame, the finger-bar, and a brace extending from the front sill of the main drive-wheel frame to the platform back of thefinger-bar, the latter being secured thereto, whereby the finger-bar is supported at its inner end by said brace and the main drivewheel frame, platform, and finger-bar are braced, substantially as described.

2. A front sill and bracing, B B, of a single piece of material, bent or curved in shape to form a front sill to a main drive-wheel frame 7 and a brace and connection for the grain-re- 1 CHARLES WVHITNEY.-
